Question
(shader code and picture of issue at bottom)
I have a shader that I detached from a mesh and then tried to re-attach, but now shows up completely black, which it didn’t before.
I’ve tried attaching albedo texture to the shader material but it’s still black. Anyone got a solution so i can get the texture back?
SHADER CODE:
shader_type spatial;
render_mode blend_mix,depth_draw_opaque,cull_disabled,diffuse_burley,specular_schlick_ggx;
uniform vec4 albedo : source_color;
uniform sampler2D texture_albedo : source_color,filter_linear_mipmap,repeat_enable;
uniform float point_size : hint_range(0,128);
uniform float roughness : hint_range(0,1);
uniform sampler2D texture_metallic : hint_default_white,filter_linear_mipmap,repeat_enable;
uniform vec4 metallic_texture_channel;
uniform sampler2D texture_roughness : hint_roughness_g,filter_linear_mipmap,repeat_enable;
uniform float specular;
uniform float metallic;
uniform sampler2D texture_normal : hint_roughness_normal,filter_linear_mipmap,repeat_enable;
uniform float normal_scale : hint_range(-16,16);
uniform vec3 uv1_scale;
uniform vec3 uv1_offset;
uniform vec3 uv2_scale;
uniform vec3 uv2_offset;
uniform float fov = 60;
void vertex() {
UV=UV*uv1_scale.xy+uv1_offset.xy;
float scale = 1.0 / tan(fov * 0.5 * PI / 180.0);
PROJECTION_MATRIX[0][0] = scale / (VIEWPORT_SIZE.x / VIEWPORT_SIZE.y);
PROJECTION_MATRIX[1][1] = -scale;
POSITION = PROJECTION_MATRIX * MODELVIEW_MATRIX * vec4(VERTEX.xyz, 1.0);
POSITION.z = mix(POSITION.z,0,0.99);
}
void fragment() {
vec2 base_uv = UV;
vec4 albedo_tex = texture(texture_albedo,base_uv);
ALBEDO = albedo.rgb * albedo_tex.rgb;
float metallic_tex = dot(texture(texture_metallic,base_uv),metallic_texture_channel);
METALLIC = metallic_tex * metallic;
vec4 roughness_texture_channel = vec4(0.0,1.0,0.0,0.0);
float roughness_tex = dot(texture(texture_roughness,base_uv),roughness_texture_channel);
ROUGHNESS = roughness_tex * roughness;
SPECULAR = specular;
NORMAL_MAP = texture(texture_normal,base_uv).rgb;
NORMAL_MAP_DEPTH = normal_scale;
}
